Hi Gents
Have a slight problem with my BSA R10 Mk2. Low power.
I did have a leak on my xtx Huma reg, which after ordering a seal kit, have fixed.
Changed pelets from bisley mags to Diabolo express.
Run the pellets through the chrono (F1) and the power is 737.2 which equats to 9.49 ft/lbs.
I have tried to adjust the power by the hammer spring but the max I can get it to is 752 which is 9.88 ft/lb. I can wind it a fair way in but it will not change.
Have I done something to the regulator, I was very careful, using a vernier when reassembling it after the seal change to get it correct.
Before the leak it did run at 11.2ft/lb.
thanks an advance
